yTo all whom it may concern.' y

ABe it known lthat I, FRANK KAsPAREK, a citizen ofv the United States, residing at Jeannette, in the county of 1Westmoreland and State of Pennsylvania, have invented certain 'new and useful Improvements in -Rotary Internal Combustion Motors, of

which the following is a specification.

The'invention relates to internal combustion or explosion motors of the rotary type and has for its primary objects; the pro- A vision of an improved motor of this character of greater eliiciency and simplicity than motors as heretofore constructed; the provision of `an improved arrangement of movable cylinder heads for permitting the passage of thepistons; the provision of an improved arrangement whereby the motor may be reversed; theprovision of improved means for insuring tight joints between the relatively movable parts; andthe provision of improved means for supplying the eXplo- .sive mixture employed. One embodiment of the invention 1s illustrated in the accompanying drawings, wherein "Figure 1 1s a side elevation of the motor with one ofthe side platesremoved to show the interior of the cylinder,

vFigure 2 is a transverse section through Figure 3 is a detail side elevation .of the upper portion of the motor, showing the' reversing mechanism,

Figure 4 is a detail side elevation of the lower edge of the cylinder, and shows the reversing mechanism for the lower pair of cylinder heads, l Figure 5 is. a detail side elevation of the mechanism for supplying explosive fluid to the motor, Figure 6 is a detail enlarged section through the explosion chamber, and fluid supplY cylinder on the line V-I-`-`VI of Figure 5,'an Figure 7 is a section throughthecylinder and one of the pistons.

Referring lirstto the general arrangement oi parts as shown'y in Figuresl, 2 and 5, such parts may be enumerated as follows; 1 and 0 2 are circular side plates bolted together andl out-curved near their outer edges to form the continuous annular cylinder 3; 4i 5, .6 are pistons'mounted in the cylinder; and integral with the supporting plate 7, is the drive shaft to whiclrthe plate 7 is keyed, and

'and 29. This pressure 'causes the valve 29 which carries at its end the iiy wheel -Q and drive pulley 10, 11 is a strut for supporting the right hand end of the shaft 8, 12 and 13 are movable cylinder heads mounted in the upper portion of the cylinder casing and taking against the wall 12, 14 and 15 are similar' 'heads mounted in the lower part ol' the cylinder casing, 16 and 17 are pump cylinders from which the explosion chambers are supplied, 18 is tlre tank containing the explosive fluid, and 19 'is the casing carrying thetwo explosion chambers, one of which 20, is shown in Figures 2 and 6.

By reference to Figure 7 it will be noted that the plate 7 fits loosely -between the side plates 1 and 2, and that such plate 7 is provided with a T hea'd 21 fitting in recesses in the side plates 1 and 2 at the periphery of the cylinder. In order to provide a tight joint the rings 22 are provided. By this arrangement a tight joint is secured with a 4minimum amount of friction. The combustion or explosion chamber (Figures 2 and 6) is located at the side of the cylinder to the position shown in Figure 6, .air is cornpressed above the upper end of the pistonby reason of the spring held check valves 28 to open admittm'gthe compressed air to the interior of the iston 25. At this time a second port 30 has been brought into registry with a port 31 leading to the combustion .chamber 20, and a .quantity of fluid together with a certain amount of air is forced through these ports into the chamber, the Vslpri'ri; held check valve 32 rising to permitt e" ow'. This charging of 'the combustionv chamber occurs just as the piston 4 passesi ure 6.

haust occurs through the exhaust port 34 after the piston passes the osition of the piston 5 as illustrated in igure 1. The device is startedby means of handles 54 (Figure 2) carried by the rods on which the pump pistons are carried. The cylinder eads are not designed to be operated by the direct contact of the piston therewith, but by the air which is compressed in front of the piston heads just prior to the time plhey1 would otherwise impinge upon the When it is desired to run the motor in the= reverse direction, the cylinder head 12 (Figure 1) is lowered and the head 13 raised, and admission occurs vthrough the ort 23 instead of through the port 23. T iis port 23 connects with a combustion chamber corresponding to the combustion chamber 20, which chamber is supplied from the cylinder 16 (Figure 5), the arrangement being in all respects similar to the arrangement heretofore described and illustrated in Fig The reversal of the parts is made by means of the construction illustrated in Figures 3 yand 5. .As here illustrated thc two cylinder heads 12 and 13 are-mounted respectively upon iods 35 and 36 carrying at their outer' ends the levers 37 and 38. The levers are actuated by means ofthe lever 39 pivoted on the rod 40 and having its ends in engagement with the two levers as shown -in Figure 3. By moving the handle 39 to-the left the head 12 may be lowered and thehead 13 raised to inoper ative position.l Rubber blocks 41 and 42 are provided for cushioning the upward movement of the levers 37 and 38. The rod 4() upon which the handle 39 iscarried is extended through the casing and has keyed to its other end the link 43, which link 43 actuates the lever 44 pivoted at 45. The

purpose of the lever 44 is toplace out ofoperative connection one of the rods 46 and '.47, which rods operate the4 pistons 25 in the cylinders 16 and 17. These'rods 46 and 47 carry at their lower ends projecting arms 48 and 49 provided with rollers for engaging a cam 50 mounted upon .the oper-v ating shaft 8. As indicated in Figure 5, the rod 46 is held up by the lever 44, so

A that the cam 50 is out of operative engagement with the arm 48. At this time the piston carried .by the rod 46 is in its uppermost position with' its upper port out of registration with the port leading to the tank 18. The rod 47 on the other hand is free to be moved up and down periodically by the cam 50, three reciprocations of the rod being afforded by the cam 50 for each revolution of the plate 7 to correspond with the three pistons carried by such plate. Springs 51 are 'provided for positively moving the rods'46fand 47 downwardly, and resilient blocks ,5"2fare insertedbelow the stop blocks 53 on the rods 46 and 47 in order to reduce the noise and jar.

By reference to Figure 1 it will be noted-` that a pair of cylinder heads 14 and 15 are'.

employed at the lower portion of the cylinder, to which admission occurs through the ports 232 and 233. This portion of the cylinder is provided with a combustion chamber casing 19 (Figure 2) carrying a pair of combustion chambers corresponding in all re-y spect's to the combustion chamber 20 shown in Figure 6. These combustion chambers are supplied by means of a pair of cylinders 16.

the cylinder heads 14 and 15 at the bottom of l These heads are the cylinder are operated. normally held in vertical position by means ol' springs 53, which engage the ends o 'f the levers 37 and 3e carried by the rods upon which the heads 14 and 15 are pivoted.

The position of the heads 14 and 15 is controlled by means of the lever 39 c0rrespond- The pistons in the cylinders 16 are' ing in all respects to the lever 39 shown in Figure 3.

lt will be ap arent that the inventionis not limited to tllfe use of three pistons or two sets of combustion chambers with the operating mechanism therefor, but that the number of these parts may be varled to suit conditions. It will also be apparent that the cylinder heads might be operated positively from some moving part connected with the shaft 8, or with some other moving part instead of being moved directly by the pistons themselves or by the compressed gas in front of the pistons. It will also be a )arent that various other types of movable cylinder heads might be employed in lieu of the ones illustrated. f

Having thus described 1n invention and illustrated its use, what I c aim as new --and desire to secure by Letters Patent is the following 1. In a rotary explosive motor, an annuofthe cylinder heads out of the cylinder and disconnect thelcorresponding valve.

2. a rotaryr explosive motor, anannular cylinder, apiston rotativel'y mounted 'and 'fitting-thereima pair of movable cylinder heads, explosionchambers having admission openings tothe cylinder infront of each head, shifting means whereby either head may be moved to inoperative position, a pair of pistons for injecting an explosive mixture to the chambers, mechanism 4for o erating the pistons and means operated by t e shifting means for moving o ne of the pistons to inoperative position whenl the corresponding head is moved to inoperative position.

3. In a rotary explosivemotor, an annu' p lar cylinder, a piston rotatively mounted and fitting therein, an explosion chamber at the side of the cylinder andl communicatingv therewith, a cylinder having .a port communicating with the chamber, an o ening for supplying an explosive mixture to t e cylinder, a hollow piston working in the cylinder` and provided withV openings adaptedto com'- municatey with the said port and opening at different portions of its stroke, inwardly .opening check valves in the ends of the cylindeil and piston, and means for'reciprocartmgfthe 4. Inv a rotar explosive motor having .an explosion cham er, a cylinder having a-'port communicating .with the chamber, an openf in for supplying an explosive mixture to the cy inder, a 'hollow iston .Working in the cyl?- In testimony whereof I have hereuntol signed my namein the presence of the two subscribed witnesses.
